将 1 0个恢复系 ,5个不育系按不完全双列杂交组配 ,考察其F1代株型性状的配合力。结果表明 ,剑叶长、宽、角度、株高 4个性状的遗传主要受加性效应的影响 ,分蘖角度受加性效应和非加性效应的影响 ,但主要受非加性效应的影响。不同材料的一般配合力、特殊配合力效应及其变异程度存在着差异 10 restorer lines and 5 sterile lines were grouped according to incomplete diallel cross to investigate the combining ability of plant type traits in F1. The results showed that the inheritance of four traits of flag leaf length, width, angle and plant height was mainly affected by additive effect. The tiller angle was affected by additive effect and non-additive effect, but was mainly affected by non-additive effect. There are differences between the general combining ability, the special combining ability effect and the degree of variation of different materials
